When Brock Lesnar returned to WWE the night after WrestleMania 28, it was such a surreal moment. It had never seemed possible. He'd left on such horrendously bad terms in 2004, and had became a multi-millionaire MMA legend in UFC. Even after he retired from UFC in December 2011, few people believed he'd go back to WWE. He had hated the rigours of the pro wrestling industry, what was in it for him to go back? Five million dollars and a few days work a year, as it turned out. https://www.youtube.com/watch?v=hL44KVErB7s Somehow, WWE managed to keep his signing under wraps. When his music and he walked out to confront John Cena on the April 2nd 2012 Raw, it was one of those genuine moments when the crowd just went crazy. Not since the Attitude Era had crowds lit up like that.
